Three Types of Radioactivity ... There are three types of radioactivity. Gamma rays come from the nucleus of the atom of a radioactive isotope. They are the most energetic and most penetrating of all radiation. Some radiation travel as particles not waves and is also emitted by the radioactive isotope.

Some radiation travel as particles not waves and is also emitted by the radioactive isotope. ... Beta particles are high speed electrons that travel close to the speed of light and can penetrate a hand but not concrete.
